Just asking, but can you rip models from Combat Arms Europe? It has probably one of the best weapon-selection of all games so far. Lots of variations of stuff, scopes, silencers, camos for some weapons and huge load of weapons! :)

I think you can find some help for ripping models from mpgh.net (yes, hacking site for some games), but it also has modding-section, and US and EU versions only differ on really small stuff, file format is nearly exact.
